- lOutputColumnID
Tipo: System.Int32
The ID of the IDTSOutputColumn100 object.
- lExternalMetadataColumnID
Tipo: System.Int32
The ID of the IDTSExternalMetadataColumn100 object that is linked to the output column.
- bMatch
Tipo: System.Boolean
Indicates whether the output column and external metadata columns match.
Valore restituito
Tipo: Microsoft.SqlServer.Dts.Pipeline.Wrapper.IDTSExternalMetadataColumn100
The IDTSExternalMetadataColumn100 that is mapped to the output column.
Osservazioni
This method is called to map an output column to a column in the ExternalMetadataColumnCollection of the output. When you are developing a custom data flow component, you override this method, to ensure that the external columns and the output column match, and to indicate that you want to allow the mapping to occur. For more information about working with external metadata columns, see Implementazione di metadati esterni.
